Diffraction by an arbitrary subreflector: GTD solution
TL;DR: Rahmat-Samii, Mittra, and Galindo-Israel as discussed by the authors studied the high-frequency asymptotic solution of diffraction by a conducting subreflector using Keller's geometrical theory.
Journal ArticleDOI
Realizable feed-element patterns for multibeam reflector antenna analysis
TL;DR: The radiation pattern of a feed element is approximately described by a simple function (\cos \theta)^{q} for a given element spacing of the feed array, and simple formulas for estimating the practical value of q when the element is an open-ended rectangular waveguide, a pyramidal horn, or a cigar antenna.
Journal ArticleDOI
Determination of specular points on a surface of revolution
TL;DR: In this paper, an efficient method for finding all the specular points for the special case in which the conducting surface is a part of a surface of revolution is presented. But this method is not suitable for the case of a single source and single observation point.
